5. Redundant: In this mode, IWS saves data in InduSoft Web Studio
both Primary and Secondary Databases. If EmbeddedView
one of these databases is unavailable, IWS CEView
keeps saving data only in the database that
is available. When the database that was
unavailable becomes available again, IWS
synchronizes both databases automatically.
Store and Forward: In this mode, IWS saves
data in the Primary Database only. If the
Primary Database becomes unavailable, IWS
saves the data in the Secondary Database.
When the Primary Database becomes
available again, IWS moves the data from
the Secondary Database into the Primary Primary Secondary
Database. Database Database
